When a crash in a program happens, and the debugger in launched in --auto
mode, in some cases the program terminates before the debugger has gotten
proper context on debuggee.
(Could be a watchdog in programs checking if it's debugged and terminating
itself if so).

Detect debuggee termination and still provide some information on debuggee
(threads, modules, system info). The backtrace will not be available as
no exception is gotten from debuggee.
